Step 1: The hand holding the the weight in the pendulum will release the weight and allow it to swing forward to hit the car. This is potential energy by the force of motion of the weight on the pendulum. Potential energy is the energy an object produces due to its position. The pendulum swinging is it being in motion therefore it has kinetic energy. The force shown form this could be Applied Force. Applied force is a force that is applied to an object by a person or another object. Step 2: After

Pendulum From Wikipedia‚ the free encyclopedia For other uses‚ see Pendulum (disambiguation). "Simple gravity pendulum" model assumes no friction or air resistance. A pendulum is a weight suspended from a pivot so that it can swing freely.[1] When a pendulum is displaced sideways from its resting equilibrium position‚ it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released‚ the restoring force combined with the pendulum’s mass

Although the exact date of when rockets were first invented is still unclear‚ it is believed that the Chinese invented the first “rocket” (“The History of Rocket Science”). Moreover‚ the Chinese used gunpowder‚ invented in around 100 A.D‚ and positioned it in Bamboo sticks for religious festival tradition (“The History of Rocket Science”). Large bamboo sticks were created and decorated by Monks and villagers‚ then blasted skyward to inform the Rain God Phaya Thaen that it is time to send rain down

In 1932‚ stone artifacts were found alongside mammoth bones in Clovis‚ New Mexico that supported this theory. In recent years‚ however‚ new evidence and discoveries challenge those beliefs. These new discoveries pre-date the Clovis artifacts and are located in different parts of North and South America. Along with those new

Many advanced high school and college chemistry students perform an experiment known as the "iodine-clock" reaction‚ in which hydrogen peroxide reacts with iodide to form iodine‚ and the iodine subsequently reacts with thiosulfate ion until the thiosulfate has been consumed. At that point‚ the reaction solutions turn blue in the presence of starch. The experiment helps students understand the fundamentals of chemical kinetics --- the speeds at which reactions take place. 1. Activation Energy

‚‚4(y STRATEGY CLOCK Whereas Michael Porter’s generic approach to competitive advantage gives substantial prominence to low cost‚ Cliff Bowman’s’ Strategy Clock’ looks at generic competitive advantage from a purely market-based perspective (MBV). He argues that competitive advantage is of no value unless it is of value to the customer and that a customer will always have a preference for such products or services over those of competitors. This may seem obvious but managers do sometimes fail to
